Whenever I open photoshop it looks as if my entire page has been zoomed out making everything on my page very very tiny and illegible. I would like to know how I could fix this it seems to be a settings issue but I can't figure out how to change it back to normal!

This is the Photoshop Touch for tablets forum; were you referring to Photoshop CC?

Do you have a high-DPI display and are using Windows? Try Edit > Preferences > Experimental Features and turn on "Scale UI 200%". (Be aware this is for high-DPI displays only.) Also try Edit > Preferences > Interface to change the size of UI text. (Photoshop > Preferences > Interface on Mac.)
